Controlled in-line spray coating to improve surface behavior and line performance

Various materials, such as PET and Tritan®, can exhibit surface characteristics that can significantly impact production efficiency. Friction, sticking, and inconsistent container movement often lead to jams, micro-stops, and accelerated wear on downstream equipment.

Delta Engineering’s automated spray coating systems apply ultra-thin coatings exactly where needed, improving container handling, reducing line disturbances, and keeping production running smoothly. The result is higher overall equipment effectiveness (OEE), fewer interruptions, and a more predictable, cost-efficient operation. In addition, the appearance of containers and bottles is preserved by significantly reducing scuffing and scratching.

Spray coating

Our spray coating systems apply thin, uniform coatings to the outside of plastic bottles, containers, and pails. By improving surface properties and reducing friction and sticking, they stabilize product flow, minimize line stops, and support high-speed, automated production. The coating also helps keep bottles glossy and scuff-free, preserving their appearance for premium applications.
